' To all whom it mn/y concern: l serve to drive the traction wheels G,G, inde Be it known thatI,W Hmmv Do'uopendently one of the other, bymechanisms LAB, a citizen of the'United States, and a resialike inconstruction, so that it sufiices to dedent of Belleville, in the countyof Essex and scribe but one in detail. v State of New Jersey,haveinvented a new On the shaft H of each motor H, H is seand ImprovedDrivi Mechanism for Motorcured a inion J in mesh with a gear wheel K,Vehicles, ofwhich t e following is af full, having its shaft K journaledin a suitable clear, and exact description bea L attached to thecorresponding The object of the invention is to provide a rnotor or H.-A casing-N supported by 10 new and im roved' driving mechanism for thebearing'L incloses and protects the gear 'motor vehic es, arr ed todrive tractionwheel K and the pinion J as lainly indiwheelsindependently rom different motors, catedinthedrawin'gs. v Thehub of theear to allow yi'e ding of the vehicle bod relative wheel K is connectedby a connecting s aft O with the wheel shaft on which t e corto eithertraction wheel, without turbing 15 or affecting the independentdrivingmechresponding traction wheel G or G is secured,

the said connecting shaft 0 being connected anisms for the tractionwheels.

The invention consists of novel features by a'universal joint Q with thesaid hub K and by a universal joint R with the inner cup-shaped head Pof the shaft P. 1 e

- he connecting shaft 0 is made in two sections 0, O, telescopingl onein the other,

the section 0' having as ead 0, provided with longitudinally extendingslots 0, en-

gagedby frictionrollers O, journaled on studs 0, held on the shaftsection 0 Thus by the arrangement described, the sections 0'', O arefree to slide or telescope one on the other, and at the same timethesections 0,

0? turn in unison.

The universal joints Q and R are preferably in the form of crosses, asplainly indicated in the drawings, one arm of the universal joint Qbeini ournaled in bearings K wheels and the connecting driving shaft forattached to the hu K of the gear wheel K,

The one of the drivengear wheels and the uniother arm of the universal 'oint Q ispivotversa'l 'oint mounted in the gear wheel, and ally connected witha-fork 1 formed on the 40 Fig. 8 is an enlarged sectional plan-viewofinner end of the shaft section 0, and the the universal jointconnecting ong'of the otherarm of the universal 'oint R is pivotdrivenshafts withthe corresponding traction ally connected with a fork a)formed on the wheel shaft.

By the arrangement desaid stub axl'es are mountedto turn the front scribed, t e gearing shaft'O is free to lengthen ortraction wheels G, G or to shorten according to the motion of the Twomotors I.I.,1l-l-v f any approvedconwheel G or G. relative to thevehicle body A, struction are suspended by brackets .I, I" and theuniversal'jointsQ and R permit free 5 from the vehicle body A, and thesaid motors turning of the wheels G or G in elther direcand-parts andcombinations of the same, which will be more fully described hereinafter2 0 and then pointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a ,part of this s ecification, in whichsimilar characters of re ere'nce indicate 25 corresponding parts in allthe views.

Figure 1 is a side elevation of the improve ment as applied to anautomobile, parts being in section; Fig. 2 is a front elevation of thesame; Fig. 3 1s a sectional plan view of 80 the same; Fig. 4 is anenlarged cross section of the improvement; Fig. 5 is an enlargedsectional plan view of the universaljoint connection between one of thedriven gear tion without undue binding so that the power of the motorsis roperl transmitted to the traction wheels and G The crosses formingbthe universal joints Q1 and R are prefera 1y made hollow, as p ainlyindicated in Fig. 5, to form lubricant receptacles for lubricating thecrosses in their bea K, P in their connections with the for O of theshaft 0. The crosses form' the universal joints Q and R are also provied with grooved collars Q R extending'in the bearings K, 1, and filledwith a packing, to com letely exclude from the said bearings and P.

'It is understood that by arr the motors H and H one in front of t eother and with their shafts H extend' transversel parallel to each otheran same 4 orizontal. plane, it is possible to mount and use powerfumotors on the vehicle body,

without unduly widening the traction'base' of the vehicle and withouttaking up too much room, and allowing a compact ai'rangement of the drigear. 7

By arranging t e pinions H and gear wheels K at opposite ends of themotors, as

shown, the transverse axes of the ear wheels.

K are causedto coincide and to ie in a vertical lane passing through theaxle C and the ivots D, D for the stub axles E, E.

awing thus described my invention, I
